A valve actuator is movable in a first direction to actuate a first valve, whose output is dependent on the position of the actuator and is movable in a second direction through a gate " from a point in the first movement to actuate a second valve. In the embodiment shown, a handle 53 is rotatable about an axis 45 by movement through a slot 70 and rotates a member 41 formed with a cam surface 43. Such movement varies the loading of a spring 10 of a well-known type of self-lapping valve 2. A sleeve 60 surrounds the rod 52 of handle 53 and is loaded by a spring 61. The end of the sleeve is bevelled and sides of slot 70 are similarly bevelled. When the handle is in the position 73, it may be moved into slot 71 on withdrawing the sleeve 60. Movement in the first part of the slot causes the handle to pivot about 47 to actuate the second valve, which may be an on-off or self-lapping valve. If a further part of slot 71 is provided, i.e. parallel to slot 70, movement of the handle along this part actuates the valve 2. In a modification, the slot 70 may be lengthened and an adjustable stop provided normally preventing movement in the extension but allowing movement when the stop is moved manually or in response to fluid pressure. The handle may be provided with a pawl-and-ratchet.

Abstract: 1,077,740. Automatic frequency control systems; radio signalling. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. Sept. 16, 1964 [Sept. 21, 1963], No. 37911/64. Headings H3A and H4L. In a satellite communication system using groups of frequency channels and pilot frequencies for each group, all transmitted as single sideband signals to the satellite, each Earth station receives back a separately transmitted pilot frequency which is compared with that originally transmitted, to form a control loop adjusting the signal frequency band position, by varying a transmitted or sub-carrier frequency, so that Doppler and other frequency errors are compensated. The satellite may retransmit a frequency modulated wave including the pilot frequency from the Earth station. At a second Earth station each received group pilot frequency may be compared with a standard frequency to produce a control voltage correcting any frequency shift in the received group frequency band. This correction may be effected by frequency changing the group frequency band by a fixed frequency, then oppositely frequency changing it by the fixed frequency altered by an amount corresponding to the control voltage. Each group pilot frequency may be transmitted at a higher level prior to the channel being used.

Patent GB-829696-A (GB)
Title: Anion exchange resins and method of preparation thereof
IPC: C08F2/00
Filed: 1956-12-18
Abstract: An anion-exchange resin is made by reacting an aromatic vinyl polymer with a complex formed of a mixture of a formaldehyde source, a halosulphonic acid, e.g. chlorosulphonic acid, and a polar oxygen-containing liquid to form an insoluble and infusible, cross-linked resin containing active side chains which is then further reacted with an amine whereby functional anionexchange groups are attached to said active side chains.  The polymer may be a solid or in solution and may be derived from styrene, vinyl toluene, alpha-methyl styrene, vinyl xylene, ethylvinylbenzene, monochlorostyrene, vinyl naphthalene or vinyl anthracene or may be a copolymer of a vinyl aromatic monomer with a non-aromatic monomer such as vinyl chloride or acrylonitrile.  The polymer may be linear or may be partially cross-linked, e.g. with a minor amount of divinyl benzene.  The formaldehyde source may be gaseous formaldehyde, formalin, or preferably a reversible polymer such as paraformaldehyde, hexamethylene tetramine, trioxane, or polyoxymethylenes, e.g. tetraoxymethylene.  The polar oxygen-containing liquid is a non-solvent for the polymer and may be water or an alcohol, ketone, aldehyde, liquid carboxylic acid or nitroparaffin of low molecular weight, e.g. acetone, acetaldehyde, dichloracetic acid, butanol or preferably methanol. A swelling solvent, e.g. ethylene dichloride, may also be present.  In the re-use of spent methanolic reaction medium an inert substantially non-polar solvent may also be added such as petroleum ether, carbon disulphide, diethyl ether, nitroparaffins or chlorinated aliphatic hydrocarbons, e.g. carbon tetrachloride, methylene chloride, ethylene dichloride, tetrachloroethane or perchloroethylene.  The product is then reacted with a primary or secondary amine such as methylamine, dimethylamine or a polyethyleneamine such as diethylenetriamine, triethylenetetramine, or tetraethylene pentamine or with a tertiary amine such as trimethyl-, triethyl- or tripropylamine, dimethylethylamine, dimethylethanolamine, methyldiethanolamine, diethylethanolamine, n - butyl - diethanolamine, benzyldimethylamine or pyridine.  In the case of aliphatic tertiary amines this amination is preferably carried out after, or while, the resin is being treated with a small amount of an aromatic or heterocyclic base, e.g. picoline, lutidine, aniline, dimethylaniline or pyridine, to avoid breaking the resin particles.  Prior to contacting with amines the polymer may be swollen by a suitable liquid, e.g. benzene or methylene chloride. Quaternary ammonium products may be treated with alkali to form strongly basic anion-exchange resins.  The process may be used to prepare ion-exchange resins from beads of the linear polymer produced by suspension polymerization or in the form of membranes or other structures produced by moulding the linear polymer.
